Hi, that's intentional, because we see that most of the time superscript input is only one character, you can press arrow left to go back and input more characters.

Maybe in future I should have a setting to turn off that feature/behavior.

Thanks.

OK I feel a bit silly because I didn't realize you could just press left and go back to editing it. It's not even unintuitive, this is exactly the behavior of e.g. grapher, which I use all the time, I really have no excuse.
